A customizable system for image browsing, named PIBE, is proposed. In details, PIBE provides the user with a set of browsing and personalization facilities that enable an effective and efficient exploration of the image collection. The approach is novel and appealing because: 1) the personalization actions over the hierarchical organization of images are local, 2) the storage of the browsing structure is persistent, and 3) the provided GUI makes browsing and personalization facilities extremely intuitive and "easy-to-use".
